44 claims. (ol. 5ta-L27) Y This invention relates to one type of sweeprakes in which the head that carries the raking teeth is pivotallymounted on a frame that is supported by a tractor, the power Vof whichis utilized not only to push the rake forwardly in hay gatheringposition but also to rock the pivoted head so thatthe raking teeth maybe raised from the ground to facilitate transporting the hay.

The principal object of my invention is to provide certain improvements,in rakes of the type above referred to, which improvements have to doparticularly with the manner and the means by which the rake is mountedon the tractor.

More specifically the objects of my invention include the provision ofmeans `for attaching the rake to the tractor so as to relieve thetractor ofV certain strains, as when the rake is loperatedover roughground. lAnother object is to provide detachable means for connectingand supporting the rake from the tractor in a flexible manner.

Other objects and advantages of my invention will be apparent to thoseskilled in the art after a consideration cf thev following detaileddescription, taken in vconjunction with the accompanying drawingswherein like numerals refer to likel parts and in which:

Figure 1 is a plan view of the rake, with the relative position kof thetractor shown in Ydotted lines;

Figure 2 is a side elevation of the rake shown mounted on the tractor,the full lines showing the rake in raking position and the dotted linesshowing the rake` in elevated or transport position; I Y

Figure 3 isa cross-sectional view taken along the line 3--3 of Figure 2;and

AFigure, 4 is anenlarged cross-sectional view taken along the line 4 4of Figure l.

Referring to the drawings, theY reference numeral 1 indicates thetractor generally, andthe tractor is provided with the usual frontsteering wheels 2 carried by steering arms 3 pivotally mounted at theends of a front 'axle 4; At the rear of the tractor the usual drawbar 6is provided supported from the tractor in any known manner, as by lugs 8mounted on or formed as apart of the housings 9. The drawbar 6 of thetractor is provided with a central flattened portion l0 for a purpose tobe described later.

The frame of the rake comprises two inner longitudinal beam members 13and two outer slightly upwardly inclined beam members 14. angle iron l5extends transversely across the members 13 near the center thereof andis bolted to the top thereof by means of bolts 16. The rear angle iron`15 extends also to the longitudinal beam members 14 and to which itis'secured, as by bolts 17. The longitudinal members 14 do not extendrearwardly farther than the rear angle '60 iron 1.5. Y A

An angle iron 19, similar to the rear angle iron 1'5, extends acrosstherfront of the'inner longitudinal members 13 and is bolted thereto, asby bolts 20. The outer longitudinal beam members 14 are secured to theangle iron 19 by bolts 21. The rear angle iron or transverse member 15is braced by diagonal braces 23.whieh are fastened tothe under side ofthe angle iron' 15 and to the sides of the inner longitudinal beammembers 13.

The brake head comprises forwardly extending rake teeth 25 which areintended to be connected to a transverse shaft or tubular member 26 andto a rear transverse connecting beam 27. Therake head is provided with anumber of vertical upstanding arms 29, each of which include a verticalsupport 30 and a diagonal support 31. These upstanding arms 29v serve tosupport two rear boards 33.

On the underside and at the ends of the rake head a runner or shoe 35 isprovided. Each of these runners or shoes takes the form of asemispherical member and is bolted to a bracket 36 by means of a countersunk bolt 37. The bracket 36 is bolted at the rear end of each of thetwo end 35 rake teeth by means of the same bolts by which the teeth arefastened to the tubular membery 26 and theftransverse connecting beam27;

The rake is pivotally mounted at the forward end of the outerlongitudinal beam members 14 90 by means of brackets 40, when secured tothe forward end of each of the longitudinal members 14. The shaft ortubular .member 26 is journaled in the ends of the brackets 40 so thatthe rake' is pivotally mounted for rotation about 95 the axis of theshaft or tubular member 26.

The angular position of the rake on the frame is controlled by means ofa connection to the power lift crank 42 on the'tractor 1. Thisconnection comprises a link 43 pivoted at its rear 100 or poles 51, theends of which are pivotally connected to the ends of the'arms 49,respectively. At its front end, each link or pole 51 is provided withtwo extension brackets 53 bolted thereto, and each of the brackets 53has a longitudinal slot 54 formed in the end thereof. A small block ispositioned between the supports and 31 of the second and fourth verticalarms 29, and these blocks have pintles 55 projecting into the slotsformed in the brackets 53. A spring 57 is interposed between the forwardend of the link or pole 51 and the corresponding arm 29 for the purposeof yieldingly pressing the Yrake teeth on the ground surface. Y -v Theframe of the rake is carried by the tractor in a U-shaped bracket 60bolted to the underside of a transverse angle iron 61 which,y in turn,is bolted across the front space of the front wheel axle 4. The innerlongitudinal beams'13 rest in the two corners of the bracket 60 and areyieldingly held in position by means of al V- shaped member 63, the endsof which rest on metal pads 64 provided on the top'of the beams Y 13. Abolt 65 passes through perforations inthe supported from the tractordraw bar 6. A bearing .plate 72 is provided on the top surface of eachbeam V13 uponwhich the angle irons 69 and '70 rest. A single bolt 73passes through a hole in the center of the fiattened portion 10 ofthedraw bar 6 and a, perforation in the center of the angle irons 70.

The upper flange of the angle iron 69 is provided with an elongated slot75 which is adapted to receive the front projection ofthe center attenedportion 10 of the draw bar '6, The rear portion of the center flattenedportion 10 of the draw bar 6 is adapted to bear against the flat face ofa plate '77 fixed to the downwardly extending flange of the angle irons70 as shown in Figure 4.

The operation of therake is believed to ybeobvious from its description.When in Vgathering or raking position the teeth 25 are in the positionshown vin full lines in Figure 2. When a-load h as been accumulatedl theoperator sets the power lift crank 42 in operation 'to swing the samefrom the full line position of Figure 2 to the position shown in dottedlines. It will be observed that he crank 42 revolves throughsubstantially a half revolution, which motion through the link 43 rocksthe shaft 45 and hence the arms 49. The arms 49 thus retract the polesor links'51 which, by virtue of the connection at 54 and 55, swing therake head and teeth to the position shown in dotted lines in Figure 2,wherei upon the load accumulated is easily transported the front wheelsof the tractor are driven over the members 23, over the rock shaft 45,and the angle iron 15.l These elements are all strong enough not tobeinjured when the front wheels of the tractor are driven over them.

When the rake is to be disconnected from the tractor, the tractor isbacked, the front wheels 2 passing back over the members 23, 45 and 15,mentioned above. To aid the front wheels in climbing over the angle iron15, plates 86 are provided4 and which vare attached to the under side ofthe angle iron 15 in line with the front wheels 2.Y The plates 89 arereinforced by angle iron sections 81 placed against the vertical flangeof theangle iron l5 and bolted to the top of the plates 80.

While I have described, in connection with the accompanying drawings,the specific form in which' I prefer to embody my invention, it is to beunderstood that the invention is not to be limited to the specific meanswhich I have herein shown and described, and that, in fact, widelydifferent inea-ns may 'ce employed in the practice of the broaderaspects of my invention.
